Well, that might be helpful.
As can be seen from the photo above, both ends of the sensor are accessible at least somewhat. The problem is two-fold: I can't easily get to the "obverse" of the connector to actuate the lock and separate the connectors, and I don't know exactly how to actuate the lock. There is a red tab that needs to be pushed up and that I can do, but there may be something that needs to be pushed to release.
The service manual may go into that detail, or not. I can't find anything definitive online.
And, even once I determine how to unlock the connector, I'm not sure I can separate the two ends. It seems that the two pieces can be quite stuck, so even if I had a tool or the ability to otherwise actuate the lock, it seems I might need two pair of channel locks and another pair of hands to get it apart. And, at that point, things are getting pretty tight in there.
